Thank for your answer. I see the problem. I added a check for this compiler's behaviour in my configure script. The code of my example is a reduced version of struct iphdr defined by GNU libc's netinet/ip.h. It means that every programs using the GNU libc's IPv4 header (or its BSD variant) cannot work fine if built with tinycc. Regards, Didier
